“Cherubael” is a black creature with the ability to exile cards from graveyards for +1/+1 counters. Similar black cards include:

• “Necrosquito” — Grows with oil counters whenever another creature dies or a permanent is put into a graveyard.
• “Carrion Feeder” — Sacrifices other creatures for +1/+1 counters.
• “Kalastria Highborn” — Not a direct analog but interacts with graveyards and rewards deaths.

All these stick to black and focus on getting stronger with graveyard interaction.
